HORSE SHOE Specification of Letters Patent.

Application filed March 9, 1909.

Patented July 20, 1909.

Serial No. 482,378.

To all whom it may concern:

Be it known that I, GEORGE F. FAssETT, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Horseshoes, of which thefollowing is a specification.

My invention relates particularly to horseshoes having removable calks;and my primary object is to provide a horseshoe of the characterindicated possessing the maximum of strength consistent with the minimumof weight and having provision for securing the calks to the body of theshoe as to insure the utmost rigidity and freedom from danger ofbecoming loosened.

A further ob eot is to provide a construction having the characteristicsmentioned which also permits removability of the calks and substitutionof new ones without removal of the shoe from the horses foot.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, in which- Figure 1 represents an upper face viewof a horseshoe constructed in accordance wit-h my invention; Fig. 2, asectional view taken approximately as indicated at line 3 of Fig. l andillustrating the manner in which the wedges employed are adapted to drawthe calks firmly to their seats; Fig. 3, a similar view taken asindicated at line 8 of Fig. 1

and showing the wedge-member fully inserted and the calk secured, thewedge member being unclenched,however; Fig. 4;, a section taken asindicated at line 4tof Fig. 1; Fig. 5, a broken perspective view showingthe toe portion of the body of the shoe, the toe-call; and one of thesecuring wedges of the toecalk; and Fig. 6, a perspective view of one ofthe heel-calks.

In the construction illustrated, A represents the body of the shoe; B, aremovable toe-callqand C, removable heel-calks.

By preference, each calk is provided with a flat bearing or shoulder 1adapted to bear a -ainst a corresponding flat surface or beariiIg 2 atthe lower side of the shoe; and each calk is provided with an upwardlyextending post or posts 3 received in perforations 4 with which the bodyof the shoe is provided. The toe-call: is shown provided with two posts,or attaching-shanks, while the heel-calks are provided each with onepost,

or attaching-shank. Each post is provided at its upper end with atransverse slot 5 which has upwardly converging walls, thereby alfordinga dovetailed groove. The calks are secured by means of wedges 6 whichhave upwardly tapering sides 7 adapted to co-act with the convergingsides of the slots 5. The wedge members 6 taper somewhat lengthwise, asshown, and each wedge has its inner, or smaller end provided with a lugor projection 8 of reduced cross-section and adapted to be clenched tosecure the wedge against withdrawal. The upper surface of the shoe isprovided with slots 9 which are of suflicient width to freely receivethe wedges 6. Each slot extends transversely across the upper surface ofthe shoe at the point where it is located, one slot being providedateach of the heel portions of the shoe, and two slots being provided atthe toe portion of the shoe. The posts or shank: members 3 arepreferably of circular crosssection, but have their upper endschamfered, or beveled, as indicated at 10.

In order to secure the calks to the body of the shoe, it is onlynecessary to insert the posts or attaching-shanks through thecorresponding perforations, drive the wedge members (3 intoposition,-and then bend the clenching portions 8 to prevent withdrawal.After the calks are in position, the bearing surfaces or shoulders 1with which the calks are provided contact firmly with the bearingsurfaces 2 with which the shoe is provided. In order to insure a closefit, the bottoms 11 of the dovetailed grooves 5 are located at such adepth as to be free from contact with the lower surfaces of the wedgemembers when the calks are properly seated, and the wedge members fullyentered, as will be clearly understood from Figs. 3 and 4. After thecalks have become worn, they may be removed and new ones substitutedwithout removal of the shoe from the horses foot. It is noteworthy thatmy construction enables the posts of the calks and the securingwedge-members to extend practically flush with the upper surface of theshoe, and that the slots 9 may therefore be shallow, so that the body ofthe shoe will not be unduly weakened. It may be added'that the innerends of the wedge-members have, adjacent to the clenching-lugs, abruptshoulders, as indicated at 12. These shoulders serve as bear ings for apunch when it is desired to remove the Wedges \Vhat I regard as new, anddesire to secure by Letters Patent, is

1. In a horse-shoe, the combinationof a body provided on its uppersurface with slots and provided, also, With perforations intersectingsaid slots, removable calks having posts entered in said perforationsand having intersecting their upper end-surfaces transverse slotsprovided with sloping sur faces, and wedge nienibers extendin throughsaid slots and having sloping sur aces contacting With the slopingsurfaces of the slots in said posts.

2, In a horseshoe, the combination of a body provided in its upper facewith crosswise slots and having post-receiving perforations intersectingsaid slots, removable calks having posts entered in said perform tionsand provided in their upper ends With crossqvise clove-tail slots, andWedge-Incinbers entered in said slots and conforming to said dove-tailslots, said wedge-members having clenching-lugs of reduced cross-sectionat 25 their inner ends.
